💖 NAME 💖

okay so this is QwtSeriesStore< T > — Class storing a QwtSeriesData object. 🫶 This page is from the Library Functions Manual, bestie, and we’re folding that manual name in right here near the top instead of doing a boring header line. 💅

🌈 Detailed Description 🌈

template<typename T>
class QwtSeriesStore< T >

Class storing a QwtSeriesData object. 💖

QwtSeriesStore and QwtPlotSeriesItem are intended as base classes for all plot items iterating over a series of samples. Both classes share a virtual base class (QwtAbstractSeriesStore) to bridge between them. 🫶

QwtSeriesStore offers the template based part for the plot item API, so that QwtPlotSeriesItem can be derived without any hassle with templates. ✨

🦋 Member Function Documentation 🦋

💜 template<typename T> QwtSeriesData< T > * QwtSeriesStore< T >::data () [inline] 💜

Returns: the the series data. (Yes, the double “the” is canon in the original, no cap 😭.)

Definition at line 146 of file qwt_series_store.h.

💜 template<typename T> const QwtSeriesData< T > * QwtSeriesStore< T >::data () const [inline] 💜

Returns: the the series data. 🫶

Definition at line 152 of file qwt_series_store.h.

🌸 template<typename T> QRectF QwtSeriesStore< T >::dataRect () const [override], [virtual] 🌸

Returns: Bounding rectangle of the series or an invalid rectangle, when no series is stored.

See also: QwtSeriesData<T>::boundingRect()

Implements QwtAbstractSeriesStore.

Definition at line 184 of file qwt_series_store.h.

🧚 template<typename T> size_t QwtSeriesStore< T >::dataSize () const [override], [virtual] 🧚

Returns: Number of samples of the series. ✨

See also: setData(), QwtSeriesData<T>::size()

Implements QwtAbstractSeriesStore.

Definition at line 175 of file qwt_series_store.h.

🍓 template<typename T> T QwtSeriesStore< T >::sample (int index) const [inline] 🍓

Parameters:

  • index — Index

Returns: Sample at position index.

Definition at line 158 of file qwt_series_store.h.

🔥 template<typename T> void QwtSeriesStore< T >::setData (QwtSeriesData< T > * series) 🔥

Assign a series of samples.

Parameters:

  • series — Data
⚠️ Warning: The item takes ownership of the data object, deleting it when its not used anymore. This is the big one, bestie — ownership is on the item, and the data object gets deleted when it’s no longer used. 💀

Definition at line 164 of file qwt_series_store.h.

🦋 template<typename T> void QwtSeriesStore< T >::setRectOfInterest (const QRectF & rect) [override], [virtual] 🦋

Set a the “rect of interest” for the series. (The phrasing is iconic, and we’re keeping it. 😭)

Parameters:

  • rect — Rectangle of interest

See also: QwtSeriesData<T>::setRectOfInterest()

Implements QwtAbstractSeriesStore.

Definition at line 193 of file qwt_series_store.h.

👑 template<typename T> QwtSeriesData< T > * QwtSeriesStore< T >::swapData (QwtSeriesData< T > * series) 👑

Replace a series without deleting the previous one. 🔁

Parameters:

  • series — New series

Returns: Previously assigned series

And that’s the whole page, bestie 💅 — the footer source/version is Qwt User's Guide, the page tag is QwtSeriesStore< T >(3), and there’s no date shown on this copy, so I’m not inventing one. Mwah 🫶💖
